Background Although periprosthetic joint infection (PJI) can affect multiple joints concurrently, the majority of patients with multiple prosthetic joints present with PJI of a single joint. Data regarding the optimal management of these patients are limited. We aimed to identify the prevalence, risk factors for a subsequent PJI, and clinical circumstances of PJI in patients with multiple prosthetic joints. Methods We retrospectively reviewed the clinical records of 197 patients with ?2 total joint prostheses in place who presented with PJI from 2000 to 2017. The average follow-up was 3.6 years (range, 0.5 to 17 years). Demographic data and risk factors for synchronous or metachronous PJI were identified. The time from the initial to the second PJI and organism profile data were collected as well. The workup for other joints with a prosthesis in place at the time of the initial PJI was noted. Results Among the 197 patients with PJI and multiple joint prostheses in situ, 37 (19%) developed PJI in another jointnt. Clinical evaluation of the other prosthetic joint(s) should be carried out in all patients and aspiration of those joint(s) should be considered for patients with any of the above risk factors.

An ERAS coordinator supervised and enforced guideline compliance for 6 months. The aim of this study was to evaluate the sustainability of the ERAS program after supervision of guideline compliance was eliminated. Methods Patient outcomes and guideline compliance were compared between surgeries performed under standard practice (April 2014 to March 2015) and those performed during and after the implementation of the ERAS initiative (March 2016 to August 2016 was the implementation phase and September 2016 to February 2017 was the sustainability phase). Results Hospital length of stay decreased from 7.26 days at baseline to 5.44 days during the implementation phase of the ERAS program (p less then 0.001). https://www.selleckchem.com/products/donafenib-sorafenib-d3.html There was no significant difference between length of stay at baseline and during the 6-month sustainability phase of the ERAS program (7.10 d). There were no significant differences in rates of readmission or mortality during and after implementation. Rate of ileus decreased significantly from 13.8% during the implementation phase to 4.6% during the sustainability phase (p = 0.036). Total guideline compliance increased from 52.2% at baseline to 80.7% during the implementation phase (p less then 0.001), and decreased to 74.7% during the sustainability phase (p less then 0.001). Adherence to postoperative guidelines regressed 79.2% in the implementation phase and 68.6% in the sustainability phase (p less then 0.001). Conclusion Hospital length of stay decreased when the ERAS program was implemented and the ERAS coordinator was present on the surgical ward. Methods for sustaining guideline implementation are vital to the success of similar programs in the future.Background Patients with lumbar disc herniation may greatly benefit from microdiscectomy. Although spine surgeons performing microdiscectomy routinely obtain informed consent, the potential adverse events they disclose often vary. Moreover, little is known about what disclosures are deemed most valuable by patients. The aim of this mixed-methods study was to determine practice variations among spine surgeons in regard to the disclosure of potential adverse events during informed consent discussions for lumbar microdiscectomy and to determine which topics patients perceived to be valuable in the consent discussion. Methods A survey evaluating the frequency with which spine surgeons disclose 15 potential adverse events related to lumbar microdiscectomy during informed consent discussions was distributed among Canadian Spine Society members. Additionally, semistructured interviews were conducted with preoperative patients, postoperative patients, attending spine surgeons, spine fellows and orthopedic residents. actice variation and optimize the effectiveness of consent discussions.Background It is estimated that one-quarter to half of all hospital waste is produced in the operating room. Recycling of surgical waste in the perioperative setting is uncommon, even though there are many recyclable materials. The objective of this study was to determine the amount of waste produced in the preoperative and operative periods for several orthopedic subspecialties and to assess how much of this waste was recycled. Methods Surgical cases at 1 adult and 1 pediatric tertiary care hospital in Calgary, Alberta, were prospectively chosen from 6 orthopedic subspecialties over a 1-month period. Waste was collected, weighed and divided into recyclable and nonrecyclable categories in the preoperative period and into recyclable, nonrecyclable, linen and biological categories in the intraoperative period. Waste bags were weighed using a portable hand-held scale. The primary outcome was the amount of recyclable waste produced per case. Secondary outcomes included the amount of nonrecyclable, biological and ams in the operating room can reduce our ecological footprint by diverting waste from landfills, as our study revealed that nearly three-quarters of this waste is recyclable.Background In this study, we aimed to evaluate incidence rates and family risk of the most common childhood cancers, tumors in the central nervous system (CNS), and leukemia among individuals from Norway and individuals with Scandinavian ancestry living in Utah. Methods We used the Utah Population Database and the Norwegian National Population Register linked to Cancer registries to identify cancers in children born between 1966 and 2015 and their first-degree relatives. We calculated incidence rates and hazards ratios. Results The overall incidence of CNS tumors increased with consecutive birth cohorts similarly in Utah and Norway (both P less then 0.001). Incidence rates of leukemia were more stable and similar in both Utah and in Norway with 4.6/100 000 person-years among children ( less then 15 years) born in the last cohort. A family history of CNS tumors was significantly associated with risk of childhood CNS tumors in Utah HR = 3.05 (95% CI 1.80-5.16) and Norway HR = 2.87 (95% CI 2.20-3.74). In Norway, children with a first-degree relative diagnosed with leukemia had high risk of leukemia (HR = 2.
